3.5. Apache Commons Logging

Set the kodo.Log property to commons
to use the
Apache Jakarta Commons Logging thin library for issuing
log messages. The Commons Logging libraries act as a wrapper
around a number of popular logging APIs, including the
Jakarta Log4J project, and the native
java.util.logging package in JDK 1.4. If neither of these
libraries are available, then logging will fall back to using simple
console logging.

When using the Commons Logging framework in conjunction with
Log4J, configuration will be the same as was discussed in the
Log4J section above.

3.5.1. JDK 1.4 java.util.logging

When using JDK 1.4 or higher in conjunction with Kodo's
Commons Logging support, logging will proceed through Java's
built-in logging provided by the
java.util.logging package. For details on
configuring the built-in logging system, please see the
Java Logging Overview.

By default, JDK 1.4's logging package looks in
the JAVA_HOME/lib/logging.properties
file for logging configuration. This can be overridden with
the java.util.logging.config.file system
property. For example:

# specify the handlers to create in the root logger
# (all loggers are children of the root logger)
# the following creates two handlers
handlers=java.util.logging.ConsoleHandler, java.util.logging.FileHandler
# set the default logging level for the root logger
.level=ALL
# set the default logging level for new ConsoleHandler instances
java.util.logging.ConsoleHandler.level=INFO
# set the default logging level for new FileHandler instances
java.util.logging.FileHandler.level=ALL
# set the default formatter for new ConsoleHandler instances
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
# set the default logging level for all Kodo logs
